Leah spotted this note in the changing area at Colman Pool in Seattle, a city she describes as “the epicenter of passive-aggressive communication.” Adds Leah: “I like the image of the kid’s shimmying out under the stall door as being a nifty method of floor cleaning. It’s both disgusting and passive-aggressive in the extreme!”

Christina in Marietta, Georgia says her 7-year-old daughter pointedly handed her this note when she picked up after school. “For the record,” Christina says, “The bread was fresh, just multigrain instead of whole wheat. The cheese was simply a different brand of Swiss cheese. Both were bought the day before.”

Meanwhile, Steph in St. Paul, Minnesota received this missive from her 6-year-old after running out of garlic salt to sprinkle on her “macken cheese,” thus beginning a 15-month boycott. (“Honestly though,” says Steph, “I don’t think mac & cheese is very healthy anyway, so…”)

Finally, Beth in New Jersey got this “friendly letter” sent home from school with her 7-year-old son.

Before you cry “FAKE!” — I would have filed this away in the “too-good-to-be-true,” pile, had not Deniz in Ontario stepped forward to admit that he is the mad man behind this posters. Explains Deniz: “I made this flyer because I had had enough of this STUPID CAT wrecking my flowers and window screen, but in the end all it accomplished was making my boyfriend think I was crazy. Oh, and I put my real phone number on it (stupid).”

I’ve gotta say, Deniz, you had me at “photo of similar looking cat.” This is my favorite crazypants submission in a long, long time.

Adds Deniz: “The STUPID CAT still remains at large. I have given up on planting flowers.”

"The thing that drives me bonkers at work is to open up the trash can drawer and see a cup half-full of water that was carefully placed into the trash can so it doesn't spill--in a trash can an arm's length away from the kitchen sink!

99% of the people in my office are college graduates, probably toward the top of their class. But some without enough common sense to pour the water in the sink before putting the cup into the trash can.
